Tim Woo 4 Nowadays, with the growing complexity of modern microprocessor architectures, well-designed compilers for high-level languages frequently produce more efficient code than most low-level programmers can produce by hand. Understanding of low-level will be helped in writing the drivers of devices. High High -level and low level and low -level programming languages level programming languages • complex programming skills • produce more efficient code • more abstract, easier to use, or more portable across platforms. • Such languages often abstract away CPU operations such as memory access models and management of scope. • make complex programming simpler • slower execution speed, • higher memory consumption • larger binary size in codes Performance • Close to machine language • Dealing with registers, memory addresses and call stacks • Handling the opcodes • Not support such routines (for-loop, if-then- else loop) (has to be written by a sequence of assembly codes) • Higher level of abstraction from machine language • Dealing with variables, arrays, complex, arithmetic or boolean expressions • Handling the codes in libraries • Handling routines (says for-loop, if-then-else loop) • Support other features such as string handling routines, object-oriented language features and file input/output may also be present.
